[PLAT-17842]: Ensure runtime config for exsting Performance Advisor and new Perf Advisor are separate

Summary:
This diff caused regression D44311
Performance Advisor under metrics tab was no longer available
This happened because the previous diff consolidated both old and new perf advisor under same runtime config
This cannot be done and they need to have separate flag

Test Plan:
Please refer to screenshot
